ABSTRACT:
A feed-forward flow controller is designed to calculate a target valve position from a target flow. Correction is made for liquid or gas pressure drop across the valve and for the valve flow modulating member geometry. This feed-forward action may also be used to linearize a feed-back flow control loop.
